Examples

Open database connection

Kotlin

In Kotlin,
val belleORM: BelleORM = BelleORM("test.db", "/Users/s4kib/")
val belleORM: BelleORM = BelleORM("test.db")    // DB will take place in user.home directory

In Android,
val appPath: String = getApplicationContext().getFilesDir().getAbsolutePath()  // Output : /data/data/application_package_name/files/
val belleORM: BelleORM = BelleORM("test.db", appPath)

Java

In Java,
BelleORM belleORM = new BelleORM("test.db", "/Users/s4kib/")
BelleORM belleORM = new BelleORM("test.db", )  // DB will take place in user.home directory

In Android,
String appPath = getApplicationContext().getFilesDir().getAbsolutePath()  // Output : /data/data/application_package_name/files/
val belleORM = new BelleORM("test.db", appPath)

Insert value

class Student {
    @PrimaryKey
    @AutoIncrement
    var studentId: Int = 0
    var name: String? = null
    var department: String? = null
    var cgpa: Double = 0.0
    var dateOfBirth: java.util.Date? = null
    @Ignore
    var section: String? = null
}

val student: Student = Student()
student.name = "Sakib Sayem"
student.department = "CSE"
student.cgpa = 2.3
student.dateOfBirth = Date()
belleORM.save(student)
belleORM.close()

Retrieve Values

val students = belleORM.find(Student())
for (it in students) {
    val student = it as Student
    println(student.studentId)
    println(student.name)
    println(student.department)
    println(student.cgpa)
    println(student.dateOfBirth)
    println()
}

Result

1
Sakib Sayem
CSE
2.3

Retrieve values based on condition

val condition: BelleORMCondition = BelleORMCondition.Builder()
            .eq("name", "sakib")
            .and()
            .greaterEq("cgpa", 18)
            .or()
            .startsWith("name", "sami")
            .sort("name", BelleORMQuery.Sort.DESCENDING)
            .sort("department", BelleORMQuery.Sort.ASCENDING)
            .build()

val students = belleORM.find(Student(), condition)
for (it in students) {
    val student = it as Student
    println("${student.studentId}")
    println("${student.name}")
}

Update value

// values will be updated based on this condition
val condition: BelleORMCondition = BelleORMCondition.Builder()
            .eq("name", "Sakib")
            .build()

val updater: BelleORMUpdater = BelleORMUpdater.Builder()
            .set("name", "Sayan Nur")
            .condition(condition)   // condition is optional
            .build()

belleORM.update(Student(), updater)

Delete values

belleORM.delete(Student())

Drop Table

belleORM.drop(Student())

---

Note

Tables will be created on fly if not exists using class name and columns based on class fields. Currently supported types:

• String
• Int
• Long
• Float
• Double
• Boolean
• Date (java.util)

Autoincrement annotated fields values will be skipped as that will be handled by sqlite.
